Awesome

This is Ridian, R in Obs idian

literal programming with R notebooks, and Quarto rendering from within Obsidian:

What this is:

A way to run R code in Obsidian
Full Quarto compliant code chunk processing (allows for seamless transition to other editors)
Parse a note and make it Quarto compliant, then render with Quarto
A way to keep notes on Coding/Statistics with enbedded working example
A way to use Obsidians amazingsearch and links to link code snippets
A way to use R code snippets to add plots/widgets to your notes

What this won't be:

An Rstudio replacement
an positro replacement
It wont cover other programming languages (5% chance of python), here is an excelent option for that: execute code plugin

[!IMPORTANT] In the Ridian settings provide the path to your R/pandoc/quarto executables, The R executable can for example be at Mac: /usr/local/bin/R Windows: C:\Program Files (x86)\R\R-4.4.1\bin\R.exe

The plugin will try to guess the R install (and probably fail)

Disclosures and Issues:

[!NOTE]

Seculity Disclosures:

Calls on External Executables: This plugin Executes code in R, an external intepreter, code execution comes with risk, you should at altimes know whether the code is save, don't execute untrusted code. File Access: The plugin accesses temporary directories to store plots and widgets, which are then copied the Obsidian vault under the plots/ and widgets/ folders.

[!NOTE] Known Issues/To-Do:

uses absolute paths for htmlwidgets

Every note spins up an R process, if you do this for many notes you'll overwhlm memory

Only confirmed to work on MacOS on my mackbook & on Win 11's (on my macbook)

No tests and other development necessities implemented

No Contribution guilines (but help wanted!)

📥 Ridian: Manual Installation Guide for Obsidian

Here's a step-by-step guide to installing your Obsidian plugin, Ridian, using the BRAT (Beta Reviewers Auto-update Tool) plugin. This guide assumes you have Obsidian and BRAT already installed.

R package Dependecies: In R/Rstudio Install: evaluate, jsonlite & htmlwidgets packages.

Step 1: Install BRAT (if not already installed)

Open Obsidian.
Go to Settings > Community Plugins.
Click Browse and search for "BRAT".
Install BRAT and enable it by clicking Enable after installation.

Step 2: Add Ridian Plugin in BRAT

In Obsidian, go to Settings > BRAT.
Under Beta Plugins List, click Add Beta Plugin.
Paste the GitHub repository URL for Ridian:
```
https://github.com/MichelNivard/Ridian
```
Click Add Plugin.

Step 3: Install and Enable Ridian

After adding Ridian to BRAT, BRAT will automatically download it for you.
Go to Settings > Community Plugins and find Ridian in the list of installed plugins.
Enable Ridian by clicking Enable.

Step 4: Verify Installation

Once enabled, check the Settings menu for any configuration options related to Ridian.
Ensure you see options to configure or activate the plugin in Obsidian’s interface.

Step 5: Set Path to R instalation & pandoc installation

In R/Rstudio Install:

install.packages(evaluate)
install.packages(jsonlite)
install.packages(htmlwidgets)

In the Ridian settings provide the path to your R installation, which can for example be: Mac: /usr/local/bin/R Windows: C:\Program Files (x86)\R\R-4.4.1\bin\R.exe

After you set the path Ridian will adjust it for internal use (it might look different if you revisit the plugin.

Install pandoc (https://pandoc.org) and point Ridian to your pandoc install if you want to use htmlwidgets in R.

And that’s it! You now have Ridian installed and ready to use in Obsidian via BRAT.
